Hmm i mostly know him from programs on Discovery and he seemed a very likeable guy, but there has indeed been quite a bit of criticism on him :

CriticismHawass has been widely accused of domineering behaviour, forbidding archaeologists to announce their own findings, and courting the media for his own gain after they were denied access to archaeological sites because, according to Hawass, they were too amateurish.[28] Others however, including several Egyptologists, have said in interviews that most of what Hawass has done for the field was long overdue.[28] Hawass has typically ignored or dismissed his critics, and when asked about it, he indicated that what he does is for the sake of Egypt and the preservation of its antiquities.[29] Hawass has instituted a systematic program for the preservation and restoration of historical monuments, while training Egyptians to improve their expertise on methods of excavation, retrieval and preservation.[30]

You have to be very careful with this type of information. Things aren't always as they seem in war. You can't really know at this point. There are accusations that, and according to ElBaradei documents proving this, that policemen out of uniform do what in the US is known as cointelpro tactics.

The propaganda war is on full throttle, fought on several levels trying to manufacture consent about the reasonableness and "moderation" of Mubarak contra the barbaric hordes that march against him, the evil Muslim Brotherhood who is secretly behind it all (neocon line), the need for "stability" and "order" (establishment-liberal line) and none of the parties engaged in propaganda is representing the Egyptian people so that is why they understand they have to protect themselves against Mubarak's police thugs smashing up museums in order to feed the propaganda machine.
